MaxiFit Couplings

MaxiFit Couplings DN40 – DN300

Viking Johnson MaxiFit Coupling is a universal pipe coupling that is designed to accommodate plain ended pipes with different outside diameters, one fitting is able to connect steel, ductile iron, uPVC, cast iron, GRP, asbestos cement pipes and PE pipes for repairs.

MaxiFit Large Diameter Couplings DN350 – 700

Viking Johnson MaxiFit Large Diameter Couplings have a long sleeve length as standard; this is a major benefit to the installer, allowing for greater cutting tolerances and greater pipe insertion depth sealing beyond the corrosion damaged pipe ends to create a safe and permanent repair.
